Pectus excavatum

This study tested whether a program of cardiopulmonary exercise—using a stationary bike plus breathing and posture exercises—can help children aged 5 to 18 with pectus excavatum (a sunken chest). Fifty children took part, and researchers measured changes in breathing strength, ex…

This study tested if freezing the nerves between the ribs (cryoablation) could reduce hospital stay compared to standard epidural pain medicine in 50 young people aged 12-24 having Nuss surgery for pectus excavatum (sunken chest). The goal was to see which method controls pain be…

This study tested a new nerve block technique to control pain after NUSS surgery for teens with pectus excavatum. Seventeen adolescents received ultrasound-guided injections to numb the chest area, aiming to avoid opioid painkillers. Researchers measured pain scores over 72 hours…

This study tested whether using a virtual reality headset during and after chest surgery could help teenagers feel less anxious and need fewer painkillers. Fifty teens aged 13-18 having a specific chest surgery (MIRPE) were randomly assigned to use VR or not. Researchers measured…

This completed study followed 69 people with pectus excavatum (funnel chest) who had a Nuss bar removed after about 2-3 years. Researchers took 3D images of the chest at four time points to see how the chest wall changes after bar removal. The goal was to find factors that might …

This completed study looked at 61 adolescents aged 6-18 with pectus deformities (sunken or protruding chest). Researchers used ultrasound to measure diaphragm thickness and compared it to standard breathing tests. The goal was to see if diaphragm thickness could serve as an early…

This study looked at 43 people with funnel chest (pectus excavatum) to see how corrective surgery changes their heart and lung function during exercise and their overall quality of life. Researchers measured oxygen use, breathing, and symptoms like shortness of breath or heart fl…
